Rated 5 out of 5 by Love this product My husband John wanted this item for Father Day 2016. He has used it for cleaning the exterior of the house and the fence. He is extremely impressed with the easy assembly, the portability of the unit. He would definitely recommend this unit for anyone needing a pressure washer for any exterior projects. He also would say that any lady looking for a unit should consider purchasing this unit. I have actually used it myself. However I prefer inside cleaning than being out side in the heat of Arkansas.

Rated 5 out of 5 by The result of many hours of research and reading. Deciding to purchase a pressure washer capable of sprucing things up around the house quickly became an exercise in frustration after reading a multitude of various online reviews. Not specific to Generac, but reviews of different pressure washers in general. Different manufacturers, different pumps and how they are utilized mechanically (the heart of the whole machine), PSI, GPM, and warranty all need to be taken into consideration. In the end, I found myself eliminating many due to user reviews, pump orientation, price, or a combination of all. Ultimately, I decided on the Generac One Wash #6602 due to its user-friendly variable pressure (from the more delicate washing of cars to the most stubborn concrete that requires far more power), proven pump design, local availability, and overall value. I'm so glad time was spent reading in advance, because I couldn't be more pleased with this machine! Assembly is a snap and it fired up on the first pull. That was a good sign right from the "start". The first day I spent approximately 4 hours using the One Wash on our several sidewalks, a massive retaining wall, patio bricks around our outdoor fireplace, and other paving brick landscaping. The finished result of everything was simply spectacular! We have a small sidewalk that runs directly in front of our house, connecting our driveway to an alternate front door. This sidewalk is under shade nearly all day, due to a huge maple tree that filters most of the sunlight in this area. As a result, it has become darkened with mildew and weathering over the course of decades. Basically, it was an eyesore - particularly when it was wet after a rain. This sidewalk was my first introduction to what the One Wash could really do. I've attached a photo of a before and after section showing just what it's capable of - and this was straight water without the use of concrete cleaner being siphoned/mixed. The difference is just phenomenal in person. Everything is still wet in the photo. However, once it dried it was so crisp and white that it almost looked like it was bleached. Decades of mildew and other grime were literally erased before my very eyes in just a matter of a few fun hours spent with man and machine. Having used the One Wash several times since, I can easily say that this was a terrific purchase that exceeded my expectations - and can just as easily recommend it to others wanting the same.

Rated 5 out of 5 by A lot of bang for the buck. I've had my One Wash for 3 years now and it had never taken more than 2 pulls to start it up. And that's after sitting in my tool shed for 9 months. The variable pressure settings are great for different applications around the house. The wand has a comfortable feel and grip. It's the best pressure washer I've ever had or used. I ordered this after seeing it on an infomercial early one morning, something I've never done before. July 21, 2016
Rated 5 out of 5 by Best Bang For Your Buck Amazing machine. I have been looking for a gas pressure washer for quite some time now. The fit and finish is second to non. Pressure is amazing and I like that you can select different pressures for different situations. The rubber handle feels great and the trigger isn't hard to hold down unlike other models I have owned. I found the hose and gun storage worked perfect. I wish I could include a picture to show how I store everything. Definitely recommend this machine. You will not be disappointed. July 12, 2016
Rated 5 out of 5 by Great machine The engine starts easily and is quiet. The washer performs very well. The only thing I don't like is the hose storage and would really wish the hose was not as stiff. May 6, 2016
Rated 3 out of 5 by Evaluate Construction Overall good specs on paper. However look at how it is built. Here are the downsides: 1. Handle is made out of plastic. Don't try to lift this unit using the handle or you will likely break it. 2. Handle has fold down pivot joints. In theory this sounds great! But in practice this is the weakest part of the handle assembly, they should not have put in this useless feature. It saves very little space, and reduces the integrity of the unit as you can no longer lift it up via handle without feature of breaking the plastic hinge joint. May 4, 2016
Rated 5 out of 5 by Works Great ! Works really well easy to set up you'll be happy you got it. Thanks Generac April 7, 2016
Rated 5 out of 5 by Great Price for a great product I couldn't be happier with my purchase of the Generac Power OneWash. I have been waiting for spring to arrive to be able to get it out and use is again for the season. I am a disabled veteran, and have difficulty walking and use a cane. This washer has been easy for both my wife and I to use. April 7, 2016
